Specific features of washing high-porous filter media

Summary

The results of studying the process parameters of high-porous water filter media changing during operation, as well as the effect on the filter cycle, the time of protective action of the media, and the time to reach the maximum head loss are presented. The efficiency of design solutions for slotted drainage and distribution devices is discussed. Recommendations are given for adjusting the particle size distribution and the height of the media layer during operation to ensure the optimal filter performance.

Key words

filtering material , physical integrity , backwash rate , porosity , drainage and distribution device , slotted coating , filtration parameters
